HACKENSACK — A grand jury has indicted two Lodi men for their alleged roles in a series of firebombings at Bergen county synagogues, authorities announced today.

The panel sitting in Bergen County Superior Court found probable cause to charge Aakash Dalal and Anthony Graziano with 30 criminal charges, including attempted murder, bias intimidation and aggravated arson, Bergen County Prosecutor John L. Molinelli announced today.

Both men have been jailed since early 2012, after police uncovered instant message exchanges between Dalal and Graziano that shed light on their detailed plans to terrorize the area's Jewish community.

With Dalal allegedly egging him on, Graziano set fire to a Paramus synagogue, and tossed a Molotov cocktail into a Rutherford temple as Rabbi Nosson Schuman and his family slept inside, police said. Schuman was injured during the fire, but the family was able to escape with their lives.

Graziano was indicted on nine counts of attempted murder, three counts of bias intimidation, three counts of conspiracy to commit arson upon a synagogue, three counts of aggravated arson, and single counts of terrorism, hindering terrorism, possession of destructive devices and hindering apprehension.

Dalal is facing three counts of bias intimidation, three counts of conspiracy to commit arson upon a synagogue, two counts of aggravated arson and single counts of terrorism, hindering terrorism, possession of destructive devices and hindering apprehension.

If convicted, both could face decades behind bars.

As of Friday, Graziano was being held at the Bergen County Jail in Hackensack on $2.5 million bail, while Dalal was held on $5.5 million bail.
